Daseul Ham, Sunghwan Park: 2 females (EMKU). Description: Medium sized Perlodinae, males brachypterous, females slightly brachypterous (Figs. 17–18). Forewing length: holotype male 7.5 mm, male paratypes 6.5–7.5 mm, female paratypes 10.0–11.0 mm; body length: holotype male 14.0 mm, male paratypes 12.0– 12.5 mm, female paratypes 15.0– 15.5 mm. Sexual dimorphism regards size, terminalia and different wing length: female wings terminate above tip of abdomen while male wings do not cover terminal segments; shortened male wing has less crossveins but branching Radial vein. Setation generally short and dense. General colour dark brown, contrasting pale pattern on wings and appendages. Head and pronotum entirely dark brown; tentorial callosities and M-line hardly visible, occiput with well developed but not contrasting rugosities (Fig. 11). Eyes and ocelli black and small, ocelli located far from each other, in a regular triangle.Antenna as long as the length of body, with more than 45 slightly clubbed antennomeres. Scape bicolored: base and inner edge dark brown, apex and outer edge light brown; pedicel and the next few antennomeres are light brown, gradually darkened towards dark brown two thirds of the antennae. Palpi brown, mouthparts mostly dark brown but glossa, paraglossa and apex of labrum contrastingly pale; vestigial submental gills present (Fig. 4). Pronotum rectangular, about as wide as long, edges rounded; rugosities numerous and small. Meso- and metanotum dark brown with whitish membranes around the wing base. Forewing with contrasting pattern: costal area and anal field shiny dark brown with metallic tint, the rest of the remigium off-white; venation brown, darker in the costal area. Hindwing is less contrasting, mostly brown with dark brown costal area (Figs. 2–3). Ventral surface of thorax contrasting: membranous areas white, while sclerotized plates brown to dark brown. Legs long and slender; tibiae distinctly longer than femora, and even more slender; claws symmetrical, arolium large. Femora dark brown with contrasting pale apical ring. Basal third of tibiae dark brown, then gradually lightened towards pale brown apical third. Tarsi light brown to brown but apical half of metatarsi dark brown. Ventral sclerites of thorax (Fig. 1): Prothorax: cervical sclerites large, with bud-like gill vestiges; rounded presternum fused with small basisternum,both with a longitudinal median ridge;precoxal bridge vestigial,eutrochantin well developed; furcasternum large and triangular, fused with basisternum, postcoxal bridge and medially ridged postfurcasternum; the furcasternal area similar to the mesothoracic furcasternum–furcasternal arm–furcasternal pit complex. Mesothorax: anterior thoracal bud-like gill vestiges present; spinasternum vestigial, presternum large and triangular, fused with the small, stripe-like basisternum; trochantin stripe-like; furcasternum large and triangular, fused with basisternum; furcal pit (furcasternal arm) connecting anteriorly to arm of mesosternal ridge that continued in a long stem (furcasternal pit); areas between furcal pit and stem sclerotized but hardly delimited. Metathorax: anterior thoracal bud-like gill vestiges present; spinasternum vestigial, presternum large and triangular, fused with the small, stripe-like basisternum; trochantin stripe-like; furcasternum large and quadrangular, fused with basisternum; furcal pit connecting to lateral margin of furcasternum; sternum I fused with furcasternum. Wing venation (Figs. 2–3, 5–6): Forewing: Costal field enlarged, with many irregular, often forked or interrupted crossveins between Costa and irregular Subcosta, humeral crossvein not clearly distinguishable. Subcosta joins the unbranched Radial vein before single radiomedial crossvein in the female, well after the branching of Radial vien in the male; there are one or two crossveins between Subcosta and Radial vein, further two between Costa and Radial vein, stigma is lacking. Medial vein originates independently from Radial vein but its base is obscure, the two veins are distinctly separated well before arculus; Medial vein branches into an irregular network shortly after arculus in the female, with several crossveins, and four longitudinal veins reaching wing margin. There are 3–5 mediocubital crossveins besides arculus. Cu1 and Cu2 branching before arculus, cubital cell quadrangular, there are 8–9 cubital crossveins in the female, 3–4 in the male; Cu1 ends about the position of Radial vein ending, last 2–3 crossveins end directly in wing margin, Cu2 ends about the position of Subcosta ending. Cubital vein and A1 basally fused, branches at the anal crossvein, cubitoanal crossvein distinct in the female but lacking in the male; A1 strongly curved after the crossveins, ends about half of wing length. There are three further anal veins besides A1; A2 and A3 can be connected with a crossvein, A4 is very short. Hindwing: Enlarged costal field, Costa, Subcosta and Radial vein network is generally similar to forewing, but humeral crossvein can be identified more distinctly. Origin of Medial vein separated from Radial vein, similarly to forewing, but irregular network of its branching is with less crossveins. There are two mediocubital crossveins besides arculus. Cu1 and Cu2 branching before arculus, cubital cell quadrangular but short, there are 5–6 cubital crossveins. Cubitoanal crossvein short and connected to a basal anal cell, there is an additional crossvein between Cu2 and A1 well after half wing length. Anal field very large and as long as the remigium, the fold of the wing extending between the parallel Cu2 and A1. Additional A veins are 7–8, branching irregularly, the last Anal vein gives irregular crossveins towards wing margin. Male abdomen (Figs. 7–8, 19–20): Segments I–II are fully divided into terga and sterna by pleura, segment III with shallow posterior notch of pleura, rest of the segments are entire. Terga I–III with wide, lightly sclerotized medial field, tergum IV with small medial field, terga V–IX entirely sclerotized and unmodified, dark brown; terga I–IX with entire antecosta, lack sensilla basiconica. Tergum X full divided into hemiterga; mostly dark brown, apical portions lighter, lack sensilla basiconica. Hemiterga triangular with rounded apex, the apical halves are converging in dorsal view, and elevated in lateral view; the wide basal anchor of epiproct divides hemiterga in the basal third by more than half of segment width, apices of hemiterga divided by a gap as wide as one fifth of the segment width. Sterna I–VIII brown, gradually darkening towards the apical segments, lacks vesicle. Sternum IX forms a well developed, rounded subgenital plate, covering sternum X and most of paraproct; sternum X widely divided medially. Paraproct dark brown, triangular with narrowed apical half, ending in a blunt apex; eversible portion is lacking. Cercus as long as the length of body, with 22–24 cylindrical segments, apical ones are rather elongated; basal 4–5 cercomeres yellowish, the rest is gradually darkened towards dark brown apical half of the cercus, but each cercomere with pale apical ring. Epiproct (Figs. 7–8, 12–14, 19–20): Basal anchor large and wide, connected to large, posteriorly directed lateral arms with raised tip, stretching basal membranes.The lever arm long and curved, rather wide in dorsal view, separated from the complex epiproct tip. The epiproct tip is shaped like an elongated 8 in dorsal, straight stripe-like in caudal, and half moon shaped in lateral view; most of the surface is lightly coloured but with a wide, lateral dark stripe and a dark dorsal ridge; the apex is arrow-shaped, tip slightly down curved in lateral view, and basally connected to rounded membranous portion. Paragenital plate large and bears ventral projection; stripe-like and slightly curved in dorsal view, dorsal portion darker in lateral view and with down curved apical portion, ventral projection has caudal edge perpendicular to the dorsal portion. Lateral stylet small, not fused and hidden in the cowl in resting condition of the epiproct; curved and stripe-like, apex with a curved, acute tooth. The cowl is densely covered by setae on most of its surface, with the exception of the dorsal surface basally to lateral stylets; bears a distinct, wide field of dense, tiny golden spikes between the stretched lateral stylets, seen only in fully everted position. In everted condition of the epiproct, the lateral arms of basal anchor raised dorsad, as well the rather enlarged cowl and epiproct tip that is fully exposed. Paragenital plates only slightly change posture, holding tight the base of the cowl. The lateral stylets are turning outwards by the base of the epiproct tip, stretching the apex of the cowl into two small, apicolateral lobes, and exposing the field of golden spines in front of the epiproct tip. The everted cowl has no other lobes, its shape is blunt conical in lateral, and rectangular in caudal view. Aedeagus (Figs. 15–16): Shape and lobes of the fully everted aedeagus remained unknown, but surface armatures and certain lobes around the armatures were clearly seen after dissection. On the ventral surface, golden brown scales are forming a large T-shaped loop; the scales are irregular small plaques with raised flanges. Adjacent to the upper part of the T, a pair of small lobules present, while the lower stem of the T is connected to a larger lobe forming an upside down C, bearing a small patch of scales beneath the stem of the T. Both the paired lobules and the lower lobe bear minute colourless spicules, scarce spinules distributed also on the surface beneath lower lobe; the surface lateral and above to the T is rarely wrinkled. The dorsal surface is armed with three small patches of golden scales similar to the ventral surface but no spicules; the upper two, elongated patches are positioned on inverting lobes, while the third, rounded patch is positioned medially on a rounded lower lobe. Female abdomen (Figs. 9–10): Segments I–II are fully divided into terga and sterna by pleura, segment III with shallow posterior notch of pleura, rest of the segments are entire. Terga unmodified, uniformly brown but apical two segments are darker, all with entire antecosta. Sterna I–VII brown, gradually darkening towards the apical segments. Subgenital plate reduced to a very slightly protruded, widely rounded posterior margin of sternum VIII, slightly bulging in lateral view; sternum VIII dark brown, with an inconspicuous longitudinal pale stripe medially. Sterna IX–X unmodified, dark brown but sternum IX with a mediobasal paler area. Paraproct dark brown with paler tip, elongated and narrow triangular, ending in a blunt apex. Cercus nearly as long as the length of body, with 24 cylindrical segments, apical ones are rather elongated; basal 3–4 cercomeres yellowish, the rest is gradually darkened towards dark brown apical two thirds of the cercus, but each cercomeres with narrow, pale apical ring. Egg: No fully matured eggs are available, but one of the females contains several dozens of nearly matured eggs. These are spherical, elongated oval with 0.3–0.4 mm length and 0.2–0.3 mm diameter. The chorion is golden light brown, apparently with dense punctuations of FCIs. No traces of collar or rims can be recognized. Larva: unknown. Affinities: As for the genus. Ecology and distribution: The species was caught by Malaise traps during May, June and July. The traps were set at elevations ranging from 700 to 1300 m, along medium sized forest streams with fast flow and mixed rocky and sandy substrate (Fig. 21). The known localities are located in the Thebaek ranges, in three counties of Gangwon province (Gangwon-do): Inje-gun, Pyeongchang-gun, Jeongseon-gun (Fig. 22). Etymology: The name koreanus refers to the Korean Peninsula where this remarkable stonefly was found.

Materials examined: The specimens re-studied from Guangxi, Guizhou, and Jiangxi were recorded in Zhao (2019) and Zhao et al. (2019). Distribution: Fujian, Guangdong, Guangxi, Guizhou, Jiangxi and Zhejiang. Remarks: The shorter process lateral to the basal cercal segment has forks of different sizes and shapes and on some males are asymmetric (Fig. 5A–C). The small lateral spines present along the longer medial process on basal cercal segment varies in distance from the apex, sometimes as much as two-fold (Figs. 6A–B). In one particular male, the left and right process on basal cercal segment are completely asymmetric, with one side having a shape similar to that of specimens (Zhao et al. 2019, Mo et al. 2022) previously determined as S. jiangxiensis (Figs. 6C – D)., Published as part of Huo, Qing-Bo, Zhao, Meng-Yuan, Du, Yu-Zhou, Murányi, Dávid, Zhu, Bin-Qing & Yu, Lei, 2023, The intraspecific morphological variability of Styloperla Wu, 1935 (Plecoptera: Styloperlidae), pp. 125-137 in Zootaxa 5249 (1) on page 128, DOI: 10.11646/zootaxa.5249.1.7, http://zenodo.org/record/7685409, {"references":["Wu, C.

Habaek gen. n. Diagnosis: Medium sized, dark brown Perlodinae with contrasting pale pattern on wings and rather long appendages; vestigial submental and thoracal gills present, furcal pit anteriorly connected to mesosternal ridge. Wings with enlarged costal field in both sexes, and unbranched Radial vein in the female. Male: sterna lack vesicle, terga lack sensilla basiconica, tergum X widely divided into triangular hemiterga; epiproct with large basal anchor and lateral arm, large paragenital plate and ventral projection, small lateral stylet and densely setose cowl, large and complex epiproct tip that is not connected with wide lever arm. Aedeagus displays a distinct pattern of golden scales. Female: subgenital plate reduced. Type species: Habaek koreanus sp. n., by monotypy. Affinities: The present tribal concept of the subfamily Perlodinae recognizes three tribes, based mainly on larval and egg characters and a few distinct characters of the male terminalia (Stark & Szczytko 1984, 1988). The lack of finger-like male hemiterga preclude the new genus from the tribe Arcynopterygini, while the lack of male sternal vesicle preclude it from Diploperlini. Consequently, we classify it in the Perlodini. However, discovery of the larva and matured egg may require modification of this classification. The spherical shape of immature eggs found in the paratype females already suppose classification in Arcynopterygini, since, with few exceptions, Perlodini species have eggs triangular in cross section, but it cannot be excluded that eggs become triangular when fully matured. The anteriorly connected furcal pit and mesosternal ridge is unique among Perlodini, while usual in Arcynopterigini (Arcynopteryx, Frisonia Ricker, 1943, Megarcys, Neofilchneria Zwick, 1973, Pseudomegarcys Kohno, 1946, Skwala Ricker, 1952) and rare in Diploperlini (Osobenus Ricker, 1952 and Stavsolus). Probably more important, and supportive of the new genus being classified in Perlodini, is the presence of fully divided but widely rounded hemiterga that lacks sensilla basiconica. This type of hemiterga occur only in the Perlodini: Tadamus Ricker, 1952 and an unnamed genus sensu Inada (1996) and Shimizu et al. (2005) from Japan, Malirekus Ricker, 1952, Oconoperla Stark & Stewart, 1982 and Yugus Ricker, 1952 from the eastern Nearctic, and Susulus Bottorf, Stewart & Knight, 1989 from California. The arrow-like apex of the epiproct tip is another character shared in only a few Perlodini genera (Dictyogenus Klapálek, 1904, Hydroperla Frison, 1935 and Isogenoides Klapálek, 1912) and not known in the Arcynopterygini and Diploperlini. The extreme reduction of the female subgenital plate is unique among the Perlodinae, though poorly produced subgenital plate is characteristic for the Pacific East Asian Megaperlodes and the Californian Salmoperla Baumann & Lauck, 1987. The presence of thoracic gills is characteristic for the Arcynopterygini. The new genus is the only Perlodini where thoracic gills are documented; however, gill vestiges are small and can be easily overlooked. Submental gills may both be present or lacking in all three tribes. In the Perlodini, more or less developed submental gills are present in Helopicus Ricker, 1952, Hydroperla, Isogenoides, Malirekus, Susulus, Tadamus, Yugus and the new genus. There are four genera of Perlodidae that are characterized by an entirely dark head and pronotum: Hemimelaena Klapálek, 1907, Levanidovia, Tadamus Ricker, 1952 and the new genus. Surprisingly, three of these are restricted to the southern temperate Pacific area of Asia and classified in the Perlodini, though they are apparently not closely related. Contrasting dark and pale wing pattern is rare among the Asian Perlodidae; besides the new genus, patterned wings are known for Megaperlodes tiunovi Teslenko, 2015 and Filchneria zhouchangfai (Chen, 2020), both of which belong to the Perlodes genus group sensu Zwick (1997). The enlarged costal field and unbranched Radial vein of both fore- and hindwings are unique among Perlodidae, and can be regarded as apomorphies. The enlarged costal area (and unusually large, rounded anal field of hindwing) is reminiscent of the Antarctoperlarian family Eustheniidae, but it surely does not reflect on phylogenetic relations with that basal family. The unbranched Radial vein of the female is unique among the Plecoptera. Etymology: The new genus is named after the Korean water god Habaek.

Kamimuria simplex (Chu, 1929) http://lsid.speciesfile.org/urn:lsid: Plecoptera.speciesfile.org:TaxonName:7456 (Figs. 1–4) Perla simplex: Chu, 1929: 88; Claassen, 1940: 145. Kamimuria simplex: Wu, 1938: 200; Du, Sivec & He, 1999: 61; Sivec & Stark, 2008: 137; Stark & Sivec, 2013: 117, nomen dubium; Yang & Li, 2018: 31. Supplementary description: Male coloration mostly dark brown to black (Fig. 1A); area between eyes to ocellar triangle dark and ventrally most parts of head and thorax yellowish (Fig. 1A–B). Male metasternum and sterna 3–7 with setal brushes (Fig. 1A). Terga 1–7 unmodified. Sensilla basiconica patches occur both as a round dark spot present on posterior tergum 8 and a median longitudinal dark area of tergum 9 that is much denser (Fig. 2A). Hemitergal lobes are slender, hooklike, extending backward to the posterior margin of tergum 9 (Fig. 2A). Aedeagus membranous; basal half with paired patches of large spines mediolaterally on the swellings; distal half with two paired swellings (Fig. 2B–C), the apical pair are larger than the basal pair; apex with dense fine spines ventrally, and a pair of ventrolateral patches of thicker and long spines arranged in “C” shaped semicircles (Fig. 2D). Female coloration similar to male (Fig. 3A–B). Abdomen brown; sterna 6–8 slightly sclerotized medially. Subgenital plate with a pair of posterolateral lobes of which apex rounded and adjacent to each other; the notch between the lobes “Ω” shaped, darker than other parts of the plate (Fig. 4). Nymph: Unknown. Egg: Unknown. Material examined: 12 males, 2 females, China: Fujian Province, Wuyishan City, Mount Wuyi, on the way from Sangang to Yiliping, Tongmu Bridge, 240 m, 27.746808 N, 117.688634 E, 2021-V-15, leg. Huo Qing-Bo, Zhao Meng-Yuan. Distribution: China (Zhejiang, Fujian). Remarks: In the area close to the type locality, our specimens ar e the onl y known Kamimuria with black body color and bright yellow anterior margin of wings, which best match the original description of Chu (1929) and Wu (1938). The species was considered as nomen dubium by Sivec & Stark (2008) and Stark & Sivec (2013) but listed as valid by Yang & Li (2018). We agree with the latter opinion since this distinctive species can be recognized on the basis of its original description., Published as part of Huo, Qing-Bo, Xiang, Ya-Nan, Rehman, Abdur, Du, Yu-Zhou, Zhu, Bin-Qing & Murányi, Dávid, 2022, Review of Kamimuria (Plecoptera: Perlidae) from Zhejiang and Fujian provinces, China, with notes on the morphological variability of K. tienmushanensis Wu, 1938, pp. 273-284 in Zootaxa 5214 (2) on pages 274-277, DOI: 10.11646/zootaxa.5214.2.7, http://zenodo.org/record/7385106, {"references":["Chu, Y.
